What each ingredient does

Fresh slaked lime
Makes the brine strongly alkaline, which slowly gels the egg white and darkens the yolk.
Coarse sea salt
Adds salinity to the brine, helping preserve the eggs and slow spoilage.

The step that matters

Keep the eggs fully submerged and upright. Eggs must stay covered by the alkaline liquid so the lime can work evenly through the shell and membrane. Exposed areas can spoil or dry, and an upright egg keeps its air cell at the top, which helps it set evenly.
